'FILING TARGET.

Application filed April 27, 1921.

To all whom, t may concern:

Be it known that l, WALTER C. TRnLoAR, a citizen of the United States,residing at Mitchell, in the county of Davison and State of South akota,have invented certain new and useful Improvements in rFiling Targets, ofwhich the following is a specification.

lThis invention relates to new and useful improvements in measuringinstruments, more particularly to devices for determining the depth ofgrades and ditches, known as tiling targets, and the primary object ofthe invention is to provide a device of this character which can be setup for operation by one man and quickly and readily applied to use andthe depth andgradegdetermined.

Still another object of the invention resides in providing a device ofthis character which may be made of wood, metal or Wood and metal, asdesired, and the stai? of which is provided with graduations, thuseliminating the necessity of using a rule separately in connectiontherewith.

Another object of the invention resides in providing a device comprisingan upright and levels adjustably carried thereon, said levels beingadapted for support on the upright and on surveyors depths hubs disposedin the ground.

A still further obj ect resides in providing a device which is simpleand durable in construction, inexpensive to manufacture, and one whichis very eihcient in operation.

With these and other objects in view my invention consists in the novelfeatures of construction, combination and arrangement of parts as willbe hereinafter referred to and more particularly pointed out in 'thespecification and claims.

In the accompanyingI drawing, forming a part of this application- Figurel is a side elevation of a device constructed in accordance with myinvention and applied to use; the dotted lines indicating attachment inusing'the device for the deep ditch digging.

Fig. 2 is a perspective view of one of the levels removed;

Fig. 3 is a side elevation of a modification of my invention;

Fig. l is a perspective view of the clamp removed.

In describing the invention l: shall refer to the drawing in whichsimilar reference characters designate corresponding parts Serial No.464,884.

throughout the several views, and in which l designates an uprightformed preferably of wood and provided with graduations on two sidesthereof, the one being in feet and inches, and the graduations on theopposite side being in tenths and hundredths, the latter not beingdisclosed in the drawing.

One side edge of the upright at its lower end is cut away to receivetherein a metal prong or' the like 2, which is secured in place by meansof screws so that the outer face of the prong is Hush with thefouterface of the upright, and this prong extends some distance below thelower end of the upright so as to support `the latter above the ground,which is designated in the drawing as The lower end of the upright asshown in Fig. l, is supported on a surveyors depth hub 4.

The depth at the hub is known and it is therefore only necessary to'operate in connection with the graduations andthe sta' or upright l. Alevel 5 is provided which has the metal arms orprojections 6 thereon,said arms beingadapted forcontact with the front and rear faces of theupright 1, and a thumb-screw 7 is applied in connection with the arms 6so as to lock the latter in frictional contact with the upright at Aanydesired and adjusted position thereon.

An angular brace 8 is carried on the under face of the level and athumb-screw 9 carried at the outer end thereof is adapted for engagementwith the side edge ofthe up-V right l so that the level may be held inits adjusted position and properly supported. Usually, three of thesetargets are used in tiling and in looking over the levels one mayreadily determine whether the targets are accurately set.

ln using the device disclosed in Fig. l it is placed upon the level ofthe ground with the upright l supported in the vertical position, and asan illustration let it be supposed that the ditch to be dug will be fivefeet. The level 5 is then adjusted to a point to correspond to thisheight or to the first graduation above the surveyors hub li. rlhree ofthese devices are used and are arranged at predetermined distances alongthe ditch to be dug. lWith the devices arranged as stated,

the operator sights over the level 5 and sighting over a six foot staffand over these levels he can readily indicate whether or not the ditchhas been dug to the required depth. Should the staff stand above thelevels then he would know that the ditch has not been dug to therequired depth.

In digging ditches of a greater depth, the level l2`is employed as shownin the modification in Fig'. 3 o1c the drawings. In this instance itr isadjusted by means of the metal arms 18 and the thumb screw I4- similarto the arms 1G and the thumb screw 7 of the level 5 along; the staff land this staff is supported in the ditch while the level 5 acts as abrace for supporting; the upper end of the upright l. Anchoringelements10V and 1l areengaged with the brace level 5 and driven into the groundto hold the device in a perpendicular position. With the parts in thisposition the level l2 is used in the same manner as the level 5 as set'forth above.

From the fore-going;` description of the construction of my improveddevice, the operation thereof will be readily understood and it will beseen that I have provided a simple, inexpensive and e'tiicient means forcarrying` out the objects of the invention.

While I have particularlydescribed the elements best adapted to performthe functions set forth, it is. obvious that various changes in theform, proportion and in the minor details of construction may beresorted to without departing* from the spirit or sacriiicing any of theprinciples of the invention. j

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A device of the class described comprising an upright havinggraduations thereon, a level, means for slidably supporting said levelon said upright, an angular bracing` member carried by said level anddesigned for contact with the side edge of said upright, and meanscarried by the bracing member for contact with the upright to adjust thelevel with respect to the latter.

2. A device of the class described having graduations thereon, a levelslidably supported on said upright, means for retaining said level invarious adjusted positions on the upright, an angular bracing` membercarried by the level and adapted to contact with the side edge of saidupright, and a thumb-screw carried on said bracingmember iior Contactwith the upright to. adjust the level with respect to said upright.

3. A device of the class described comprising a graduated standard,supporting' means associated therewith, a level having arms eX- tending:trom the sides thereoi` and adapted to receive said standardtherebetween, and a clamp associated with the free ends of said arms tohold said level in its adjusted position on said standard. Y

1I. A device of the class described adapted for use in deep ditchdigging, comprising a graduated standard adapted to extend verticallyinto said ditch, a level adjustably carried by the lower end of saidstandard, a brace adjustably carried by the upper end of said'standard,and means associated with said brace and adapted to be driven into the vground for holding said standard in a vertical position.

In testimony whereof I aiix my signature.

WALTER GTRELOAR.
